My truck is a 2014 w/ 50k miles. I started bone stock, save for a oiled cotton-style filter (Green Filter)....i.e. no tune, etc.Did you get into the computer and change the tire size? If so, how did you do it?
I adjusted to mid-perched, bought an SCT tune w/ 5-star tunes. Once I got to the tire store I flashed the 93 octane street tune and re-cal'd the speedo for the new tire size. Seems the new tune more than compensated for whatever I lost with the larger diameter, heavier tire, because the truck feels just as strong as ever (stronger even). My current mileage reads 12.7. I was getting 13.1 prior to the tires and tune (it was at 12.8 when I posted a few days ago, but I've been doing a lot of sitting and idling lately; I expect it will come back up).
And, best of all, 37s are just sexy...

Thanks for the vote of confidence...but, no, I'm not quite that stupid.LOL Yeah most people don’t realize the speedo/odometer don’t know your actual tire diameter unless you have the nGauge or similar that will let you change it. If you switch from 35” to 37” without changing ECU tire data then the measured distance will be less for a given distance, so your inficated mileage will be less. Your mpg, distance, and road speed will indicate less than actual.

Can't speak for the V6/rice-burner Raptors. I was talking about the ones that are actually "trucks” (jk).
